Repair Corrupt RX100 Video Files

This method fixed my corrupt video from when my RX100Va’s battery died in the middle of recording an h264 mp4 video. 

I downloaded and tried repairing it with a variety of other free and paid software. This is the only one that worked for this particular file.

It requires a Windows machine with admin access.
